Description
Technical field
The present invention relates to a kind of LED and steep lamp, particularly relate to the fit structure of a kind of LED bubble lamp lamp holder.
Background technology
LED bubble lamp, compared with common electricity-saving lamp, has the advantages such as light efficiency height, little power consumption, life-span length, is the most increasingly subject to
Favor to people.But, the caloric value of LED bubble lamp is higher, it is necessary to arrange normally making of radiator structure guarantee LED bubble lamp
With.
As depicted in figs. 1 and 2, the radiating mode of existing common LED bubble lamp includes being passed by heat by heat-conducting piece 4 '
It is directed on the shell 2 ' of plastic material, then conducts to lamp holder 3 ' place.Heat-conducting piece 4 ' and shell 2 ' they are to be connected with face by face, but
Because heat-conducting piece 4 ' is metal material, it is unlikely to deform, and shell 2 ' is plastic material, easy dilatancy of being heated.Furthermore heat conduction
In the fabrication process, there is certain tolerance in the two for part 4 ' and shell 2 ', and the assembling being likely to result in heat-conducting piece 4 ' and shell 2 ' is
Interference fit, so that shell 2 ' ruptures because of the support force by heat-conducting piece 4 ', affects conforming product rate；It is likely to cause heat conduction
There is gap in the assembling of part 4 ' and shell 2 ', causes the conductivity between heat-conducting piece 4 ' and shell 2 ' to lower, have influence on heat radiation.
In view of this, the design people is perfect caused all for not attaining in above-mentioned LED bubble lamp lamp holder matching structure design
Many disappearances and inconvenience, and deeply conceive, and actively research improvement has a fling at and develops and design the present invention.
Summary of the invention
It is an object of the invention to provide a kind of lamp holder fit structure, the heat-conducting piece that can improve radiator structure is joined with shell
While closing stability, it is ensured that lamp body heat dispersion.
In order to reach above-mentioned purpose, the solution of the present invention is:
A kind of lamp holder fit structure, it includes a lamp holder, a shell coordinated with lamp holder and the heat-conducting piece with shell；Wherein:
The inner surface of described shell forms the ring of a protrusion and coordinates with the circular base of heat-conducting piece bottom, described ring inner surface periphery
Several protuberance is distributed, protuberance the internal diameter surrounded passes through protuberance and heat-conducting piece less than pedestal external diameter, i.e. ring
Pedestal forms interference fit.
Described protuberance is sharp tooth.
Described protuberance is wavy.
After using such scheme, the internal diameter surrounded due to the shell ring inner surface protuberance of the present invention is less than outside pedestal
Footpath, then pedestal coordinates in setting with ring, embed during, due to the top lifting surface area of protuberance is little and exist between
Gap, pedestal meeting extruded protrusion also makes protuberance deform, and the flash of deformation can be inserted in the gap between each protuberance, so that
Ring is resisted against on the pedestal of heat-conducting piece completely, it is ensured that shell and heat-conducting piece junction do not have gap, and coordinate easily, surely
Gu, it is effectively improved stability and yields that heat-conducting piece coordinates with shell.
It addition, heat-conducting piece sets with shell to coordinate can ensure that the two effective contact area, make the heat of heat-conducting piece to the greatest extent
Possible is delivered on shell, further ensures the thermal diffusivity that lamp body is good.

Detailed description of the invention
In order to technical scheme is explained further, below by specific embodiment, the present invention is explained in detail
State.
As shown in Figures 2 to 6, present invention is disclosed a kind of lamp holder fit structure, be imposed in LED bubble lamp, this LED steeps
Lamp includes shell 2 that a lamp holder 1, coordinates with lamp holder 1, drives the wiring board 3, of LED chip operation to coordinate with shell 2
Heat-conducting piece 4, several are distributed LED lamp bead and coordinate chip 5, on heat-conducting piece 4 to connect chip 5 and wiring board 3
Dual platen 6 and a cover are placed in the cell-shell 7 outside heat-conducting piece 4 and chip 5；Wiring board 3 is placed in heat-conducting piece 4；The present invention's
It is critical only that:
The inner surface of described shell 2 forms the ring 21 of a protrusion and coordinates with the circular base 41 of heat-conducting piece 4 bottom, described ring
21 inner surface peripheries are distributed several protuberances 22, protuberance 22 internal diameter surrounded is less than pedestal 41 external diameter, i.e. ring 21
Interference fit is formed by the pedestal 41 of protuberance 22 with heat-conducting piece.
Coordinate as it is shown in figure 5, described protuberance 22 is preferably sharp tooth.Certainly also can as shown in Figure 6, described protuberance 22
For wavy.
When described shell 2 coordinates assembling with heat-conducting piece 4, the internal diameter surrounded due to ring 21 inner surface protuberance 22 is less than
Pedestal 41 external diameter, then pedestal 41 coordinates in setting with ring 21, during embedding, due to the top stress surface of protuberance 22
Amassing little and there is gap, pedestal 41 extruded protrusion 22 also can make protuberance 22 deform, and the flash of deformation can insert each protuberance
In gap between 22, so that ring 21 is resisted against on the pedestal 41 of heat-conducting piece completely, it is ensured that shell 2 and heat-conducting piece 4 connect
Place does not haves gap, and coordinates easy, firm, and by the setting of this protuberance 22, makes the tolerance fit that shell 2 is processed more
Easily support is held, and shell 2 is difficult to be occurred bursting, and is effectively improved stability and yields that heat-conducting piece 4 coordinates with shell 2；It addition, heat conduction
Part 4 is set with shell 2 to coordinate and be can ensure that the two effective contact area, outside making the heat of heat-conducting piece 4 be delivered to as far as possible
On shell 2, it is ensured that the thermal diffusivity that lamp body is good.
The above, only present pre-ferred embodiments, do not limit the scope that the present invention implements, skill under this invention with this
Equivalence change and the modification that art scheme and description are made, all should belong to the scope that the present invention contains.
